Re: Third axis for Lathe mode

Marty, I think you were asking for a machine picture in your first reply. Now attached. I also checked for errors on the Mill installation. i only saw one. I have no idea how to track down the errors. I haven't noticed anything unexpected working with the machine. I also attached a report from the m...

Third axis for Lathe mode

I have Acorn installed on a mill turn. I want to be able to run the bridge up and down when in the lathe mode. Sometimes it would be handy to put an indicator in it and use it to sweep the QTC holder for alignment,... I have enabled the third axis as Y and have it where is homes and will go up and d...

Mecsoft doesn't seem to have a Centroid post processor for lathe. Anyone done one?

That is what I had done. I also measured from the bridge to the lathe bed and that is the same. It is pretty noisy though

Re: Z Axis noise level

Thanks for the feedback Marty. Yes, left Accel at .5sec. I think I will slightly loosen the timing belt to see if popping goes away. It has been so long since the original machine ran, I can't remember if it was noisy. I do know it would never move like that! You can clock the ball nuts 1/4 turn for...

Re: Spindle Voltage Offset

Me personally, I wouldn't get overly excited about your called vs. Actual. Your high and low are close. If you really want to TRY and get it closer, you have to experiment with the settings IN the VFD. Nowforever sounds like a Chinese drive. (Good luck with support and assistance) Spindle Test.JPG ...

Z Axis noise level

I continue to work through the startup of my Mill Turn conversion. Acorn/CNC12 rocks! My Z axis is significantly louder than the X and Y. The X and Y are direct drive ball screws. The machine is like a bridge mill in the milling mode so the Z axis is mechanically more complex than X and Y. There are...
